Version 3.2.0 of ImageStream's Enterprise Linux is now available as an general release for all ImageStream router customers. This software release is provided at no charge to all ImageStream customers. Version 3.2.0 is highly recommended for all customers. VERSION 3.2.0 PROVIDES A PATCH TO NEW VULNERABILITIES PRESENT IN PREVIOUS ENTERPRISE LINUX RELEASES. SPECIFICALLY, NEW VERSIONS OF SSH AND SNMP ARE INCLUDED IN THIS RELEASE. See "Limitations and Upgrade Instructions" before upgrading. This release note documents commands and features added between Version 3.0.3 and the Version 3.2.0 release. ---------------------------- New Features in Version 3.2.0 Boot Times Significantly Reduced Version 3.2.0 contains an efficiency update to the router boot procedure. Routers running Version 3.2.0 should boot approximately 50% faster than under previous versions. OpenSSH Upgraded To OpenSSH 3.1p1 The version of OpenSSH included in Version 3.2.0 addresses recent security advisories. Version 3.1p1 included with this release does not allow users to pass environment variables to login when "UseLogin" is enabled and is not affected by the "Off-by-one error in the channel code" advisory. Base-libraries Package Updated The version of the Base-libraries package included in Version 3.2.0 addresses a vulnerability in the zlib compression library. Although no exploits for this issue are known to exist, this potentially serious vulnerability has been patched in this release. Base-networking Package Updated The version of the Base-networking package included in Version 3.2.0 addresses a buffer overflow vulnerability in the netkit utilities for ping, ftp, telnet, in.telnetd and inetd. Previous versions of netkit used by ImageStream are not vulnerable, but the programs have been updated as a precaution. net-snmp Upgraded To Version 4.2.2 The version of net-snmp included in Version 3.2.0 addresses multiple vulnerabilities in trap and request handling in version 1 of SMNP. Although no exploits for this issue are known to exist, this potentially serious vulnerability has been patched in this release. Backup Flash/Restore Flash Options Added To Menu Previous Enterprise Linux versions omitted "Back configuration up to flash" and "Restore configuration from flash" menu options. These options were previously available only from the command line but have been added to the menu as well in Version 3.2.0. Memory Test Boot Option Added Version 3.2.0 adds a "Memory test" option to the router boot menu. Selecting this option from the boot menu will load a memory testing program that automatically examines the RAM installed in the router for any physical problems or errors. A thorough memory test may take several hours to complete, so this boot option is recommended for use during maintenance windows and for routers able to be removed from service for long periods of time. ---------------------------- Bugs fixed in Version 3.2.0 The following bugs have been fixed in Version 3.2.0: Console Configuration File Fixed The console configuration file in earlier Version 3.0 releases has been replaced with a non-binary version. The default values used for the console control program were not affected, but users can now reconfigure the console control program properly. Gated Menu Options Fixed Earlier Version 3.0 releases failed to correctly reconfigure Gated after configuration changes were made from the router menu. The OSPF configuration option in the router menu also failed to open the gated.ospf file. Version 3.2.0 corrects these behaviors. Various Aesthetic Changes To Menu Options Version 3.2.0 fixes small typographical errors in all of the router menus, and adds clearer descriptions of several menu items. ---------------------------- Limitations and Upgrade Instructions *** NOTE! If the upgrade fails, do NOT reboot! Contact ImageStream's Technical Support without rebooting. *** Limitations Upgrading to Version 3.0 or later requires the following: 1. 64 MB of RAM or higher. 2. 32 MB of flash. 3. 300 MHz processor or better. 3. Enterprise Linux Version 2.3.2 or higher. The upgrade utility will not install Version 3.0 if memory and flash requirements are not met. Users can contact ImageStream to purchase a RAM, processor or flash upgrade. Users running an Enterprise Linux version less than 2.3.2 must upgrade before Version 3.0 will be available from the Update menu. Upgrading any version prior to 2.3.2 will automatically be upgraded to 2.3.2. A second upgrade will be required to install Version 3.0. The upgrade does not otherwise affect the stored configuration in the ImageStream router. To back up the router's configuration prior to upgrading, choose option 4 (Backup/Restore) from the router's main menu. Choose the Backup methods option (Option 1) and select a method from the choices listed. From the router's command line, use the "backup " command. The backup utility takes four arguments: flash (to back up configurations to the router's nonvolatile flash memory), floppy (to back up to a floppy disk), scp (to back up via secure copy), or file (to back up to a separate file on the router's nonvolatile flash memory). ---------------------------- Copyright and Trademarks Copyright 2002 ImageStream Internet Solutions.
